Thermal expansion tanks are like insurance policies...useless until
the tipping point in the system is passed, then a $$ saver. You can't
prevent municipal bureaucrats from modifying water systems with
antibackflow valves or other EPA mandated gadgets which will affect
your water system. So a 2 gallon expansion tank at around $100 makes
sound economic sense. The alternative would be a capped and vented
standpipe tall enough to allow equilibrium with local water pressure.
Of course, the neighbors might not like a 100' tall (or more) pipe
poking up in the yard. Even disguised with vines or dressed up as a
cell tower it couldn't pass most building codes. Oh well...
